Multi-medium cards case structure

ABSTRACT

The present invention relates to an improvement of a MMCard case including a cuboid with at least one storage space formed, wherein, an opening facing outward formed on a side to allow the MMCard to be placed in; an edge strip formed at each outer lateral side of storage spaces, with grooves formed thereof; a hinge connector formed on both ends of each groove thereof; by inlaying hinge connectors into positioning holes formed on each shaft end of a dual-shaft, each dual-shaft thereby hinged at each groove, enabling the two cuboids rotating freely about the dual-shaft. Many cuboids can be hinged this way to fulfill requirement, thereby making it easy in keeping, filing, viewing, inlaying, and removing MMCards.

BACKGROUND OF THE INVENTION

a) Field of the Invention

The present invention relates to a case for multi-media cards, and more particularly to a structure that connects cases thereof to facilitate keeping and filing multi-media cards.

b) Description of the Prior Art

Due to rapid evolution in integrated circuits technique and electronic material, products such as electronic dictionaries and digital cameras etc are all electronic gismos developed, which require large memory to process data or images. Instead of applying large-volume computer related memory devices, a mini memory cards, known as Multi-Media Card (MMCard), was invented.

Unfortunately, the MMCard can be too fragile in handling, therefore a specific case was designed. Referring to FIG. 1. A conventional MMCard case 20 includes four storage spaces 21, each having a spring structure 22 formed on a bottom, wherein a MMCard 10 can be inlaid in or pressed down for removing. Several MMCard cases 20 can be stacked by fasteners through holes 23 on a side thereof. Deficiencies of a conventional MMCard case 20 are as follows,

-   -   1. The MMCard 10 surface, being pressed to contact with the         spring structure 22, may be damaged during being inlaid in or         removed.     -   2. The stacked MMCard cases 20 is inconvenient either in         removing the MMCard 10 or in viewing for a needed MMCard 10.     -   3. Number of stacked MMCard cases 20 can be limited by length or         volume of fasteners.

SUMMARY OF THE INVENTION

It is an objective of the present invention to provide a structure improvement of a multi-MMCards case to enable connecting multi-MMCards cases for storing and filing purposes.

It is another objective of the present invention to provide a structure improvement of a multi-MMCards case to enable spreading out multi-MMCards cases for easy viewing purpose.

It is yet another objective of the present invention to provide a structure improvement of a multi-MMCards case to enable inlaying and removing MMCards without causing any damage thereof.

To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 2 and 3. The present invention is a structure improvement of a multi-MMCards case comprising:

-   -   a cuboid 30, including four storage spaces 31 formed in two by         two array, each with an opening 32 facing outward, wherein on         each inner surface of each lateral side of the openings 32, an         inwards directed positioning flake 33 formed on an upper and an         inwards directed projection 34 of a spherical structure with a         curved flake formed on a bottom near the opening 32; at each         outer column side of storage spaces 31, an edge strip 35 formed,         with at least a groove 36 formed thereof, each with a hinge         connector 38 formed on each end 37 thereof;     -   at least a dual-shaft 40, parallel to each other, wherein a         positioning hole 42, corresponding to the hinge connector 38 of         the groove 36, formed on each end 41 thereof;

Referring to FIGS. 2˜4. One of the dual-shaft 40 is hinged at grooves 36 by inlaying hinge connectors 38 into positioning holes 42, thereby the dual-shaft 40 can be rotated freely around the edge strip 35 of the cuboid 30.

Referring to FIGS. 5˜7. The dual-shaft 40 hinges two cuboids 30 at grooves 36 by inlaying hinge connectors 38 with positioning holes 42, thereby cuboids 30 thereof can rotate around the dual-shaft 40. With the grooves 36 formed within the edge strip 35, appearances will not be affected by un-hinged grooves 36 on both ends of the three hinged cuboids 30. With the three hinged cuboids 30 stacked together, volume will be minimized, thereby facilitating storing and filing. With three hinged cuboids 30 spread out, each MMCard 10 on the storage space 31 is visible, thereby placing or removing or viewing MMCard 10 can be easy. The MMCard 10 can be inserted into the storage space 31 from the opening 32 through the guidance of projections 34 and positioning flakes 33. With the projection 34, the MMCard can be prevented from slipping out of the storage space 31, thereby keeping MMCard in good care.

It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims. 

1. A multi-MMCards case comprising: a cuboid, having at least one storage space, each with an opening facing outward formed on a side, wherein on each inner surface of each lateral side of the openings, an inwards directed positioning flake formed on an upper and an inwards directed projection formed on a bottom near the opening; at each outer lateral side of storage spaces an edge strip formed, with grooves formed thereof, each having a hinge connector formed on each end thereof; at least a dual-shaft, wherein a positioning hole formed on each end of each shaft; by inlaying hinge connectors with positioning holes, one of the dual-shaft thereby hinges at the groove, enabling the dual-shaft to rotate freely on the edge strip of the cuboid; by pushing the MMCard into the storage space from the opening enables the MMCard to keep within four contacting points formed by projections and positioning flakes.
 2. The MMCard case as recited in claim 1, wherein the cuboid further comprising four storage spaces.
 3. The MMCard case as recited in claim 1, wherein the projection being formed as a spherical structure with a curved flake.
 4. The MMCard case as recited in claim 1, wherein the projection being formed inside and near the opening on a bottom of each lateral side thereof.
